How to deploy a Teams-Toolkit app that uses an external API to a client?

[ArneJanning]

I am using Visual Studio 2022 (Version 17.12.3 ) with the Teams Toolkit-Integration.

I used the "Chat With Your Data"-Template and selected Azure OpenAI, as we are Azure OpenAI customers.

Then I changed the RenderDataAsync()-method to call an external API that I have built and return the output to Teams:

public async Task<RenderedPromptSection> RenderDataAsync(ITurnContext context, IMemory memory, ITokenizer tokenizer, int maxTokens, CancellationToken cancellationToken) { string? query = memory.GetValue("temp.input") as string;

if (query == null)
{
    return new RenderedPromptSection<string>(string.Empty, 0);
}
else
{
    using var httpClient = new HttpClient();
    var requestUri = "http://<domain-name>/query";
    var requestBody = new
    {
        query = query,
        mode = "local"
    };

    var json = System.Text.Json.JsonSerializer.Serialize(requestBody);
    var content = new StringContent(json, Encoding.UTF8, "application/json");

    using var request = new HttpRequestMessage(HttpMethod.Post, requestUri)
    {
        Headers =
        {
            { "accept", "application/json" }
        },
        Content = content
    };
    var response = await httpClient.SendAsync(request);
    var responseContent = await response.Content.ReadAsStringAsync();
    var answer = responseContent;
    return new RenderedPromptSection<string>(formatDocument(answer), answer.Length);
}
}

This works without problem when I test it locally, I can also import the appPackage.dev.zip and publish the app to my Office-365-org and it just works as expected.

But what do I have to distribute to my client in a different Office-365-org? If I give him my appPackage.dev.zip he is able to install it but the bot never gets any response, I don't even see any requests being made to my API.

What am I missing?
